This was really cool! It's always interesting to see how people can take "simple" mechanics like Plinko and use them to make something entirely different (Like that one roguelike, Peglin, that did a similar think with Peggle). Putting the player on a timer, then having everything, including going to the shop, take days away from that timer was a smart decision. It actually makes deciding what to do meaningful.
Also, after I died I got stuck on the screen telling me I was being sent back to my ship and that I had lost a few days. I'm not sure if there was a confirm button or something that was hidden (or I missed), but I couldn't figure out how to progress from that screen after that.
